About this Guide
This guide contains systematic disassembly instructions for the Packard Bell EasyNote ST. The
instructions are illustrated where necessary with images of the part that is being disassembled.
Packard Bell B.V. reserves the right to make changes to the EasyNote ST without notice.
For More Information
For more information about the Packard Bell EasyNote ST, visit Packard Bell‘s support web site at
www.packardbell.com
. The support web site also has links to additional Packard Bell
documentation and detailed product specifications.
Technician Notes
Only technicians authorized by Packard Bell B.V. should attempt to repair this equipment. All
troubleshooting and repair procedures are detailed to allow only subassembly/module level repair.
Because of the complexity of the individual boards and subassemblies, no one should attempt to
make repairs at the component level or to make modifications to any printed wiring board.
Improper repairs can create a safety hazard. Any indication of component replacement or printed
wiring board modifications may void any warranty or exchange allowances.
Disassembly
When disassembling the system unit, follow these general rules:
î‚„ Turn OFF the power to the system and all peripherals using the power button.
î‚„ Unplug the AC adapter and all power and signal cables from the system.
î‚„ Remove any SD/MMC card, ExpressCard or dummy card from the computer.
î‚„ Do not disassemble the system into parts that are smaller than those specified in the
instructions.
î‚„ Label all removed connectors; note where the connector goes and in what position it was
installed.
î‚„ The screws for the different components vary in size. During the disassembly process,
group the screws with the corresponding components to avoid mismatch when putting back
the components.
Reassembly
Reassembly is the reverse of the disassembly process. Use care to ensure that all cables and
screws are returned to their proper positions. Check that no tools or any loose parts have been left
inside the casing. Check that everything is properly installed and tightened.
Required Tools
To disassemble the computer, you need the following tools:
î‚„ Wrist grounding strap and conductive mat for preventing electrostatic discharge.
î‚„ Small Phillips screwdriver.
î‚„ Small flat screwdriver.

Hazardous Voltage
There is hazardous voltage present inside the
notebook when it is connected to an AC supply,
even when the notebook’s power switch is off.
Exposure to hazardous voltage could cause
personal injury. To avoid risk of injury, contact an
Authorized Service Provider for proper
(un)installation of optional hardware devices.
Avoid Electrostatic Discharge
Electrostatic electricity can easily damage circuit
cards and integrated circuits (ICs). To reduce risk
of damage, store them in protective packaging
whenever they are not installed in the system.
Add-in cards can be extremely sensitive to ESD
and always require careful handling. After
removing the card from the notebook, place the
card flat on a grounded, static-free surface,
component-side up. Use a conductive foam pad if
available, but not the card wrapper. Do not slide
the card over any surface.
Before you install or remove memory modules,
video memory, disk drives, circuit cards or other
devices, protect them from static electricity. To do
so, make sure the notebook’s power switch is
OFF. Then, unplug the notebook’s AC power cord.
Before picking up the device you (un)install, you
should wear an anti-static wrist wrap (available at
electronic supply stores). Be sure to connect the
wrist wrap to an unpainted metal portion of the
notebook casing. As an alternative, you can
dissipate electrostatic build-up by touching an
unpainted metal portion of the notebook casing
with one hand. Then touch the device you are
(un)installing with the other hand, and maintain
continuous contact with it until it is (un)installed in
the notebook.
Power Supply Unit
Under no circumstances should you attempt to
disassemble the power supply. The power supply
contains no user-serviceable parts. Inside the
power supply are hazardous voltages that can
cause serious personal injury. Always return a
defective power supply to the dealer.
WARNING
Ensure that the notebook is disconnected
from its power source and from all
telecommunications links, networks, or
modem lines whenever the casing cover
is removed. Do not operate the notebook
with the cover removed.
AVERTISSEMENT
Assurez-vous que le système est
débranché de son alimentation ainsi que
de toutes les liaisons de
télécommunication, des réseaux, et des
lignes de modem avant d’enlever le
capot. Ne pas utiliser le système quand le
capot est enlevé.
WARNUNG
Das System darf weder an eine
Stromquelle angeschlossen sein noch
eine Verbindung mit einer
Telekommunikationseinrichtung, einem
Netzwerk oder einer Modem-Leitung
haben, wenn die Gehäuseabdeckung
entfernt wird. Nehmen Sie das System
nicht ohne die Abdeckung in Betrieb.
ADVERTENCIA
Asegúrese de que cada vez que se quite
la cubierta del portátil, el sistema haya
sido desconectado de la red de
alimentación y de todos lo enlaces de
telecomunicaciones, de red y de lÃneas de
módem. No ponga en funcionamiento el
sistema mientras la cubierta esté quitada.
WAARSCHUWING
Zorg er voor dat alle verbindingen van en
naar de notebook (stroom, modem,
netwerk, etc) verbroken worden voordat
de behuizing geopend wordt. Zet de
notebook nooit aan als de behuizing
geopend is.
AVVERTENZA
Prima di rimuovere il coperchio del telaio,
assicurarsi che il sistema sia scollegato
dall’alimentazione, da tutti i collegamenti
di comunicazione, reti o linee di modem.
Non avviare il sistema senza aver prima
messo a posto il coperchio.
